ANTI-KICKING DEVICE FOR cows Filed Feb. 12, 1954 I N V EN TOR. O. flren Z or B 47; WW W United States Patent 2,727,493 ANTI-KICKING DEVICE FOR COWS Otto Vilhard Norenborg, Uppsala, Sweden, assignor to Aktiebolaget Separator, Stockholm, Sweden, a corporation of Sweden The present invention relates to a device for preventing cows from kicking during milking, veterinary treatment, etc.

A device made according to the invention is characterized by a frame, or the like, adapted to be placed in front of the udder and the hind-leg knees, between the pelvic brims and the thigh-joints and across the small of the back of the cow, so that the cows knees are barred. The device is effective primarily because the frame lies in front of the cows knees but also because of the pressure exerted by the frame on the parts between the pelvic brims and the thigh-joints.

For a better understanding of the invention, reference may be had to the accompanying drawing illustrating a preferred form of the new device. In the drawing, Fig. 1 is a front view of the device; and Fig. 2 is a side view of the device on a reduced scale, showing it fixed on the cow.

The device consists essentially of a frame stantially U-shaped bowl and a tightening means 2 arranged on the bow. The U-shaped bow 1 comprises two parts 3 and 4 which are hinged to one another by means of a bolt 5, or the like, at the connective part 6 of the bow. On one part 3 a stop in the form of a boss 7 is fixed, which is arranged to cooperate with the edge 8 of the other part so that the relative turning movement between the bow parts 3 and 4 is limited. The stops 7 and 8 should be so arranged that the bow shanks 9 and 10 form an angle of 70100, preferably 80, when the stops engage one another.

The shanks 9 and 10 have on their outer sides, near their ends, a plurality of notches 11 suitably arranged directly opposite each other and forming with a flexible element or chain 12 the tightening means 2 of the frame. The chain 12 is provided at its ends with rings 13 forming looped end portions adapted to receive the frame shanks 910 and fit into the notches 11.

in order to prevent loss of the chain, it is preferable to lock it permanently to the U-shaped how 1. For this purpose one of the shanks 9 is provided with a vertical rod 9a, or the like, connected at its ends to the shank above and below the notches 11 but otherwise spaced from this shank. Thus, the rod 9a prevents the adjacent ring 13 from sliding over the end of the shank 9.

When the frame is used, it is placed with its connective part 6 in front of the udder 14 and with its shanks 9 and 10 in front of the knees 15 of the hind-lcgs and between the pelvic brims 16 and the thigh-joints 17. Then the rings 13 are inserted into the notches 11 so that the chain 12 is stretched tightly. In so doing, the chain should lie across the small 18 of the cows back. Due to the location of the frame in front of the cows knees having a sub- 2,727,493 Patented Dec. 20, 1955 15, and the pressure it exerts between the pelvic brirns 16 and the thigh-joints 17, the cow is effectively prevented from kicking.

The invention is not limited to the specific embodiment described above and shown in the drawing, but may be varied in many ways within the range of the following claims.

I claim:

1. A device for milking, or the like, whlch comprises a frame adapted across the small of the cows back, and a U-shaped bow having a lower part arranged to extend in front of the cows udder and also having rigid shanks connected at their upper ends to said upper part and arranged to rest against both flanks of the cow between the pelvic brims and the thigh-joints in front of the cows hind-leg knees, whereby said knees are barred.

2. A device according to claim 1, in which said upper part of the frame includes tightening means connected between the ends of the bow.

3. A device according to claim 1, in which said upper part of the frame includes tightening means connected toward and away from each other.

4. A device according to claim 1, in which said upper away from each stops on the bow for limiting of the bow.

5. A device according to claim 1, in which the frame includes a flexible element forming said upper part.

6. A device according to claim 1, in which the frame other, and interengageable said movement of the ends tend and fitting into said notches, and a rod connected at its ends to one of the shanks above and below the notches therein to lock the flexible element to said last shank.
